Troubleshooting

This section provides solutions to common issues you might encounter while using your TopScan Lite device.

• Device Not Connecting via Bluetooth:

  Ensure the TopScan Lite is firmly plugged into the OBD-II port and the vehicle's ignition is on. Verify Bluetooth is enabled on your smartphone and that you have selected the correct device in the app. Try restarting both the app and your phone.

• App Not Recognizing Vehicle:

  Confirm your vehicle's make, model, and year are supported by checking the in-app vehicle coverage lookup. Ensure the device is properly connected and the ignition is in the correct position. Sometimes, trying a different OBD-II port (if available) or restarting the vehicle can help.
• Unable to Clear Fault Codes:

  Fault codes can only be cleared if the underlying issue has been resolved. If the problem persists, the code will reappear. Ensure all necessary repairs have been completed before attempting to clear codes. Some specific codes may require multiple drive cycles to clear automatically after repair.

• Inaccurate Readings or Data:

  Ensure the app and device firmware are up to date. Poor connection or interference can sometimes affect data accuracy. Verify the vehicle's battery voltage is stable, as low voltage can impact diagnostic tool performance.

• App Crashing or Freezing:

  Ensure your smartphone meets the minimum system requirements for the app. Clear the app's cache and data, or reinstall the app. Ensure your phone's operating system is updated to the latest version.
